Abstract :
Nowadays wireless communication for rotating electrical machines is interesting for both real time monitoring and diagnosis purposes. However, the application of this technology can lead to some problems. In fact, in our paper, the experimental results of radio monitoring system are illustrated to prove that one of the major problems of these types of application is the big received power variation range and fast fading wireless channel compared with stationary transmitter. Thus, our work aims to analyze the Electro Magnetic Wave Propagation (EMWP) characteristics in rotating environments in order to provide a strong theoretical support for developing high-performance radio monitoring system. In particular, the Doppler frequency shift in rotating movement will be analyzed.
